It is confirmed that December 21, 2012 is NOT the end.
See Matthew 24:36 where Jesus says,: 'But of that day and hour, no one knows, not even the angels of heaven, but my Father only.'
And in the 43rd & 44th verses he continues,: 'But know this, that if the master of the house had known what hour the thief would come, he would have watched and not allowed his house to be broken into. Therefore you also be ready, for the Son of Man is coming at an hour you do not expect.'
So...only God knows. That being the case, the one thing we can count on is that any date suggested by man will NOT be it! Personally, I have a party planned for that day, nearly 1,000 days away.
